I know the water is not draining from the evaporator housing drain tube. I have tried to run a cloths hanger up the tube to clear any blockage. The water would come out but the next day it would be blocked again. I took it to the shop and they too were successful in unblocking it but the next day it would not drain again. What should i do????????
